While the newest Sports Illustrated Swimsuit cover girl Kate Upton downplayed her now-famous curves in a draped look at a Las Vegas party on Thursday night, fellow model Anne V opted to flaunt all of her assets.

The blonde stunner, 25, who's been dating Adam Levine for two years, hit the red carpet in a skimpy black Anthony Vaccarello mini, which featured a plunging neckline held up by a thin piece of metal, side cut-outs and an open back.

She reportedly broke up with the Maroon 5 frontman, 32, after the duo got into a big fight in late January.

However, Levine's rep told Us Weekly that the split is "100 percent not true," and Vyalitsyna enthusiastically tweeted about the Voice premiere during the Super Bowl.
